The effects of MALAT1 from human adipose-derived stem cell (ADSC) exosomes in skin wound healing were investigated. The viability, apoptosis and migration ability of human skin fibroblasts (HSFs) were evaluated by Cell Counting Kit-8 assay, flow cytometry and scratch assay, respectively. A mouse model was established to evaluate the role of exosomal MALAT1 in skin wound healing . Human ADSC exosomes promoted the proliferation and migration of HSFs and increased MALAT1 expression. MALAT1 silencing in human ADSCs inhibited HSF viability and migration, promoted HSF apoptosis and inhibited angiogenesis by upregulating miR-378a. Overexpression of miR-378a inhibited the migration and proliferation of HSFs by downregulating FGF2 expression. ADSC exosomes promoted skin wound healing by mediating MALAT1 . Exosomal MALAT1 accelerated skin wound healing by regulating the miR-378a/FGF2 axis, suggesting that MALAT1 might be used as a potential target for cutaneous wound treatment.

Background: Contemporary research has shown that acellular dermal matrices can benefit adult lower extremity traumatic injuries; however, its use in children has not been explored.

Objective: This study aims to explore the use of acellular dermal matrices in pediatric complex lower extremity trauma.

Methods: This single-center retrospective observational cohort study of children with complex lower extremity trauma treated with Pelnac™, commercial acellular dermal matrices, was conducted at a tertiary hospital in South Africa from 2010 to 2017.

Importance: Surgery is frequently required for hidradenitis suppurativa (HS) treatment, but the impact of common comorbidities such as obesity, diabetes, and smoking on outcomes has been sparsely studied.

Observations: A total of 12 studies met final inclusion criteria for investigating complication rates associated with at least 1 comorbidity. Complication rates were associated with obesity in 3 of 10 studies.

Chronic wounds, due to their high prevalence, are a serious global health concern. Effective therapeutic strategies can significantly accelerate healing, thereby reducing the risk of complications and alleviating the economic burden on healthcare systems. Although numerous experimental studies have investigated wound healing, most rely on qualitative observations or quantitative direct measurements.
